I have got the Pat Dually and I have been using for both hunting and 3d.
I will tell you that as far as hunting goes this thing has got some clout mine is only a 60lb with a 28" draw.
On the string I have got a peep,cats whiskers,magnock reciever,2 tied in nocks and a string loop with a 345gr arrow it is doing 281fps and with a 310gr arrow it is doing 292fps.
I do use a slightly heavier arrow for hunting 370gr' s and the power it puts out is unbelieveable and it is deadly accurate.

I am thinking really hard about getting the Pro40 Dually in target colors for 3d just have to some how either tell the wife or sneak it into the house.
